Analysis of Lean Manufacturing Lean Manufacturing (Lean Manufacturing) is a Massachusetts Institute of Technology plans to organize several international car (IMVP) expert on Japan, &quot;Toyota JIT (Just In Time) production,&quot; the praise of the said fine, that few but not put into extra factors of production, but production at the appropriate time necessary number of market needs product (or the next process urgently needed products); interests, that all business activities must be useful and effective, with the economy. Lean manufacturing is a current industry best organization system and method of production. Lean manufacturing is the post-war Japan&#39;s auto industry was the &quot;resource scarcity&quot; and &quot;more variety, small batch&quot; the product of market discipline, which is starting from Toyota It&#39;s long odds, by Kiichiro Toyoda and Ohno resistance to common first-person efforts to gradually improve until the 60&#39;s formed. Lean manufacturing is a kind of production to minimize occupied resources and reduce operating costs, business management and production methods as the main target, but it also is a concept, a culture. Lean manufacturing is the determination to pursue the perfect course, is pursuit of excellence in the process, it is the support of a personal and business life of spiritual power, but also in the never-ending learning process of getting a state of self-satisfaction. The goal is to strive for excellence, perfection and never-ending pursuit of the ultimate goal of seven to zero. The essence of lean manufacturing management process, including the optimization of organization and management of personnel, efforts to cut the middle management, to organize the reform of the flat, to reduce non-direct production personnel; push synchronization of production equalization to achieve zero inventory and flexible production; implementation the whole production process (including the entire supply chain) the quality assurance system, to achieve zero non-performing; reduce and reduce any part of the waste, zero waste; eventually pull in-time production. Lean manufacturing is characterized by the elimination of all waste, the pursuit of excellence and continuous improvement. Production processes to remove all useless things in each of workers and their job is to value the principle of the arrangement, remove all non-value-added positions. Streamline its core, to streamline product development, design, production, management does not produce value-added work all aimed at the best quality, lowest cost and highest efficiency of the market needs the most rapid response. The advantages of lean manufacturing methods and significance Compared with the mass production methods, the Japanese lean manufacturing methods used in the superiority lies in the following areas: The necessary human resources - both in product development, production systems, or other parts of the factory, and factory mass production mode than the minimum can be reduced to 1 / 2; New product development cycle - the minimum could be reduced to l / 2 or 2 / 3; Product inventory in the production process - the minimum could be reduced to the general level of mass production mode 1 / 10; Factory space - the minimum could be reduced by mass production mode of 1 / 2; Finished goods inventory - the lowest mass production mode can be reduced to the average inventory level of 1 / 4; Product quality - can greatly; Lean manufacturing methods are thoroughly pursue the production of rationality, efficiency, flexibility to produce high-quality products meet the needs of the production technology and management techniques, many of its basic principles and methods of manufacturing has a positive meaning. The core of lean manufacturing, that is, the production planning and control and inventory management, the basic idea, on the enrichment and development of modern production management theory also has an important role. Lean manufacturing management features on (1) pull (pull) production time (JIT) The end-user demand for producing a starting point. Stressed that logistics balance, the pursuit of zero inventory, processing requirements a process completed parts into the next process immediately. Organization of production relies on the operation of Kanban (Kanban) for. Kanban delivery processes from demand information between (billboards of Xingshibuxian, the key is the ability to transmit information). Beat production by human intervention, control and logistics to ensure a balance in production (for each process, the following procedures shall ensure timely supply of). As a result of pull-type production, production planning and scheduling is essentially completed by the individual production units themselves, not in the form of a centralized plan, but during the operation of coordination between production units is essential. (2) total quality management Emphasis on quality is produced rather than testing out, from the quality control process to ensure the final quality. Production process of quality inspection and control in every process is carried out. Focuses on training each employee&#39;s quality consciousness, to ensure timely detection of quality problems. If found in the production process quality issues, depending on the circumstances, you can immediately stop production until the problem in order to ensure does not appear valid non-conforming product processing. The quality problems, usually related to technical and production organization staff as a team, with collaboration soon as possible. (3) Team Work Act (Teamwork) Each employee at work is not only to carry out orders. More importantly, active participation, play a role in decision-making and decision support. Organizations are not fully in accordance with the principles of the team to division of administrative organizations, but mainly divided according to business relationships. Team members emphasized the multi-skill, required to be familiar with other staff within the team, ensuring the smooth coordination. Evaluation of the performance of team members by working within the team&#39;s evaluation. The basic atmosphere of team work is trust, a long-term supervision and control oriented, while avoiding the work every step of the verification, to improve efficiency. Team&#39;s organization is changing, different things, create a different team, the same person may belong to different teams. (4) CE (Concurrent Engineering) During the product design and development, will be conceptual design, structural design, process design, the final demand combined with the fastest speed to ensure the quality required to complete. All work related to this project by the team completed. Their own arrangements for members of the group process itself, but a regular basis or at any time feedback and coordination to solve the problems. Based on appropriate information systems tools, feedback and coordination of the projects. CIM using modern technology, product research and development during the process of parallel auxiliary projects. ? Source: Allied Supply Chain Management Consulting Shanghai Co., Ltd.
